9 Best LLM Optimization Tools for AI Visibility in 2026 (Free and Paid)
By Toy Wen Da, Co-Founder · · 15 min read · scored 91/100
The best LLM optimization tools for AI visibility depend on what you're trying to fix. SearchBlueprint pairs AI visibility tracking with the SEO work that actually earns citations, which suits most small businesses. Profound fits large enterprises that need deep, multi-brand monitoring and compliance controls across nine AI engines.
This guide breaks down nine options and what each one actually does. It also shows where each one runs out of road, so you can pick one instead of guessing.
What LLM Optimization Tools for AI Visibility Actually Track
An LLM optimization tool for AI visibility monitors how often ChatGPT, Perplexity, Gemini, Copilot, and AI Overviews mention and cite your brand. Then it compares that against your competitors. Think of it as rank tracking, but for AI-generated answers instead of a list of blue links.
Most of these platforms work the same basic way. You give the tool a set of prompts, questions a buyer might ask, like "what's the best project management tool for freelancers". It then runs those prompts across AI engines on a schedule. It then reports whether your brand showed up, where, and which sources the AI cited to back up its answer.
Mentions, Citations, and the Gap Most Tools Miss
Three things typically get measured: mentions, citations, and sentiment. Mentions means whether the AI named your brand. Citations means whether it linked to or referenced your content as a source. Sentiment means whether the mention was favorable.
A smaller number of tools go further and check whether the AI got your pricing, features, or positioning right. A wrong mention can cost you a deal just as easily as no mention at all.
The practical limitation across almost the whole category is prompt discovery. You have to guess what questions people are asking AI about your industry. There's no equivalent of Google Search Console showing you the prompts that actually drove a visit. If you want a structured way to close that gap, this 30-day plan for proving AI search visibility can help. It walks through building a prompt list and tracking movement against it. Getting the technical side of your site right matters here, since AI crawlers read your pages the same way search engines do. See this breakdown of AI-driven SEO for user experience for what that involves in practice.
How We Chose the Best LLM Optimization Tools for AI Visibility
This comparison is built from each product's own website, pricing page, and documentation, not from hands-on testing of every tool. Where sources disagreed on a price or feature, we've said so rather than picking one and presenting it as fact.
Four things mattered most for this list:
- Price and whether a free plan or free trial exists. Small businesses and solo marketers usually want to test a tool before committing a monthly budget.
- What the tool is actually good at. Some are pure trackers; others bundle tracking with content creation, technical audits, or broader marketing work.
- Which AI engines it covers on the entry plan, since several vendors lock Gemini, Claude, or Copilot behind add-ons or higher tiers.
- Its honest limits, what you'd still need a second tool for.
Build a Broader AI Toolkit
If you're assembling a broader AI toolkit rather than just a visibility tracker, it's worth comparing this list against two related guides. See the best AI tools for small business and AI marketing tools with real prices. AI visibility tracking is usually one piece of a larger stack rather than the whole thing.
9 Best LLM Optimization Tools for AI Visibility in 2026
Here's the list, SearchBlueprint first since it suits the reader this guide is written for. That's a small business owner, marketer, or agency who needs AI visibility folded into real SEO work, not a standalone dashboard.
1. SearchBlueprint: best for small businesses and agencies that want AI visibility built into their SEO work
SearchBlueprint builds an SEO plan that maps each target search to a specific page. It then runs technical, on-page, and schema audits to find what's holding that page back. It handles keyword research and competitor analysis, and tracks both traditional rankings and AI search visibility. It also writes and publishes articles weekly to WordPress, Shopify, Wix, or Webflow once you approve them. It also refreshes aging content, suggests internal links, and generates white-label reports for agencies managing client sites. On top of that, it includes 60+ free SEO tools and a free SEO Academy.
Compared to the dedicated trackers later in this list, SearchBlueprint skips a few things. It doesn't do deep prompt-level monitoring across nine or more AI engines, hallucination or pricing-accuracy detection, or multi-brand enterprise governance. It tracks AI search visibility as part of the broader plan, not as a standalone, high-volume prompt tracker. If your content strategy also leans on AI-written drafts, it's worth comparing the two. See dedicated AI content writing tools and other AI SEO tools built for practitioners.
Starting price: see their pricing page (plans start free, then Base or Agency). Free plan: Yes, start free.
Pick it if: you want one plan that turns keyword research into published pages and also tells you whether AI engines are mentioning you. Skip it if: you need to track hundreds of prompts across nine AI engines with hallucination detection. That's a job for a dedicated tracker like Peec AI or Profound.
2. Peec AI: best for agencies that want flexible, daily prompt tracking
Peec AI tracks your visibility, position, and brand sentiment across a chosen set of AI engines. On paid plans, you pick three from ChatGPT, Google AI Mode, Google AI Overviews, Gemini, Microsoft Copilot, and Naver AI. Perplexity and Claude are available as add-ons or on Enterprise. It stays narrowly focused on monitoring, with prompt-level detail on which sources get cited and how you stack up against named competitors.
Reported starting prices vary by source. One comparison lists it at $89 a month after a 7-day free trial. Another cites €85 a month (about €70 if billed yearly). A third lists a $95-a-month Starter plan covering 50 prompts and three AI models. There's no permanent free plan, only a trial.
Starting price: roughly $85–95/month depending on billing, per recent comparisons. Free plan: No, free trial only.
Pick it if: you run an agency and want clean, daily tracking without content-creation features bolted on. Skip it if: you need Perplexity or Claude coverage on the entry plan, those sit behind add-ons here.
3. Otterly.AI: best for budget-conscious teams just starting out
Otterly.AI tracks mentions and citations across ChatGPT, Perplexity, and Google AI Overviews, with Copilot, Gemini, and Claude available as add-ons. Its GEO Audit feature checks on-page factors and returns recommendations for improving how likely your pages are to get cited. It's consistently named as one of the cheapest serious options in this category.
Its entry plan is $29 a month (or roughly $25 a month billed yearly). It comes with a 7-day free trial rather than a permanent free tier. If budget is the main constraint, Otterly sits alongside Rankscale and ZipTie as the cheapest dedicated trackers worth comparing. Rankscale runs around $17 a month billed yearly, and ZipTie starts from about $25.65 a month.
Starting price: $29/month. Free plan: No, 7-day trial.
Pick it if: you just want a baseline answer to "are we mentioned at all?" without a big spend. Skip it if: you need the tool to flag wrong pricing or invented features in AI answers, that's not what it checks for.
4. Profound: best for enterprise brands needing scale and compliance
Profound is built for large organizations tracking AI visibility across multiple brands, product lines, or regions in one system. It adds role-based access, audit trails, and custom dashboards so executives, marketing teams, and regional managers each see what's relevant to them. It also has API access for connecting into an existing martech stack.
Pricing is listed as custom on Profound's own site, tied to engine coverage and account complexity. One third-party comparison cites a limited entry plan around $99 a month with a 7-day trial. That scales up to full Enterprise coverage of up to nine engines, including Copilot, Claude, and DeepSeek.
Starting price: Custom, see their pricing page. Free plan: No, 7-day trial.
Pick it if: you're managing AI visibility for multiple brands or business units and need governance controls to match. Skip it if: you're a solo marketer or small team, this is priced and built for enterprise complexity you likely don't have yet.
5. Semrush AI Visibility Toolkit: best for teams already running Semrush
Semrush folded AI visibility tracking into its existing suite rather than launching it as a separate product. The toolkit covers ChatGPT, Google AI, Gemini, and Perplexity, tracking roughly 25 prompts daily on the entry plan. It sits next to the SEO data you're likely already pulling from Semrush for keyword and competitor research.
Listed pricing runs around $99 a month per domain. Sources differ on trial access. Semrush's own subscribers sometimes get a short trial window tied to their existing plan. There's no dedicated free trial for the AI toolkit on its own.
Starting price: $99/month. Free plan: No dedicated free trial for the toolkit.
Pick it if: you already pay for Semrush and want AI visibility sitting next to your SEO dashboards instead of in a separate tab. Skip it if: you don't use Semrush for anything else, you'd be paying for a platform you won't touch outside this one feature.
6. Ahrefs Brand Radar: best for large brand datasets without writing your own prompts
Ahrefs Brand Radar pulls from a database of roughly 500 million prompts. That means you get data on day one instead of building a prompt list from scratch. It covers ChatGPT, Perplexity, Gemini, Copilot, AI Overviews, and AI Mode, with Claude available through custom prompts. Ahrefs also offers a free AI Visibility Checker with no signup required, covering the same major engines for a quick first look.
The paid product starts from $199 a month, which is noticeably higher than most of the dedicated trackers on this list.
Starting price: from $199/month. Free plan: Yes, free AI Visibility Checker (no account needed).
Pick it if: you want broad competitive data immediately, without manually building a prompt library first. Skip it if: $199 a month is out of budget, the free checker gives you a snapshot. But ongoing tracking costs more here than almost anywhere else on this list.
7. Surfer: best for tracking AI visibility and fixing the content it cites
Surfer tracks five AI engines daily: ChatGPT, Perplexity, Gemini, AI Overviews, and AI Mode. It starts on a free plan, then moves to a paid tier at $82 a month billed yearly (about $95 billed monthly). What sets it apart is the Content Editor, included from the Standard plan up at around $182 a month. It shows you the facts and sources AI answers are pulling from for a given topic. That lets you edit content to match.
Surfer pairs visibility data with a content editor built to act on it. That combination puts Surfer closer to dedicated content optimization tools than to a pure tracker. It's a good comparison point if you're deciding whether to buy a tracker and an optimizer, or one tool that does both.
Starting price: $82/month, billed yearly. Free plan: Yes, start for free.
Pick it if: you want tracking and on-page content fixes without switching tools. Skip it if: you don't need a content editor, you'll pay for a feature you're not using if tracking is all you want.
8. AthenaHQ: best for covering many AI engines on one plan
AthenaHQ stands out for engine breadth. Its free plan covers five engines. Its Starter plan, at $295 a month (around $245 billed yearly), extends to 11 engines, including Claude, Grok, and DeepSeek. That's a wider spread than most competitors offer even on paid tiers. Usage is metered through credits, 300 free, 3,600 on Starter, rather than a flat prompt count.
The jump from the free plan to Starter is one of the steepest on this list. It's worth testing the free tier thoroughly before deciding whether the full feature set justifies the price.
Starting price: $295/month (Starter). Free plan: Yes.
Pick it if: broad engine coverage, including less common ones like Grok and DeepSeek, matters more to you than price. Skip it if: your budget caps out well under $295 a month. The free plan's five engines may not be enough once you need the full picture.
9. Scrunch AI: best for brand personas and AI agent readiness
Scrunch AI tracks ChatGPT, Perplexity, AI Overviews, and Copilot on its Core plan, extending to nine engines on Enterprise. Its distinguishing feature is a focus on how AI agents, not just chat interfaces, perceive and represent your brand. It also offers persona-based analysis of how different buyer types might be answered by AI.
The Core plan starts at $250 a month with a 7-day trial and covers 125 tracked prompts. That positions it closer to the enterprise end of the pricing spectrum than to the budget trackers earlier on this list.
Starting price: $250/month (Core). Free plan: No, 7-day trial.
Pick it if: you're thinking ahead to AI agents making purchasing decisions on a buyer's behalf, not just chat answers. Skip it if: you need a lower entry price, $250 a month is steep if you're just starting to measure AI visibility.
How the 9 Tools Compare
| Tool | Best for | Free plan | Starting price | Main limit |

| Otterly.AI | Budget-conscious teams starting out | No (7-day trial) | $29/month | No accuracy or hallucination detection |
| Profound | Enterprise brands needing scale and compliance | No (7-day trial) | Custom pricing | Opaque pricing, built for large teams |

| Ahrefs Brand Radar | Large datasets without writing prompts | Free checker only | From $199/month | Highest entry price among the dedicated trackers |
| Surfer | Tracking plus fixing the content AI cites | Yes, free to start | $82/month (yearly) | Full content editor is an added cost |
| AthenaHQ | Covering many AI engines on one plan | Yes | $295/month (Starter) | Steep jump from free to paid |
| Scrunch AI | AI agent readiness and brand personas | No (7-day trial) | $250/month (Core) | Priced for enterprise use cases |
When a Free AI Visibility Checker Is Enough
A free plan or free checker is enough when you're asking a simple question. Does AI mention my brand at all, roughly, right now? Ahrefs' free AI Visibility Checker, Surfer's free starting tier, and AthenaHQ's free plan all answer that without a monthly bill. For a first look before committing budget, that's exactly what they're for.
| Free option | What it covers | Good for | When to upgrade |
|---|---|---|---|
| Ahrefs AI Visibility Checker | One-time snapshot, no signup | A quick gut check before buying anything | You need ongoing tracking, not a single snapshot |
| Surfer free plan | Limited tracking on sign-up | Testing the interface before paying | You want the Content Editor or more tracked prompts |
| AthenaHQ free plan | 5 engines, 300 credits | Light, ongoing monitoring on a small budget | You need Claude, Grok, or DeepSeek coverage |
When a Free Checker Falls Short
Free stops being enough once you need to act on what you find. If AI is citing a competitor instead of you, or getting your pricing wrong, you need to act. That means a plan that tracks more prompts across more engines, or pairs the data with content work to fix it. SearchBlueprint's content refresher is one route if the fix is an aging page. A paid tracker is the route if the gap is coverage itself.
This is also where the broader content side of your strategy matters. If AI engines are citing round-up posts and third-party comparisons instead of your own site, it's worth looking at two resources. See content curation tools and AI content tools built for growth to see how that content gets built and ranked. And if your site itself needs rebuilding before any of this tracking matters, start there first. See how to choose an AI website builder rather than layering a tracker on top of a weak foundation.
FAQs
What's the difference between an LLM optimization tool and a regular SEO tool?
A regular SEO tool tracks where your pages rank in Google's list of links. An LLM optimization tool tracks whether AI platforms like ChatGPT or Perplexity mention and cite your brand directly in a generated answer. That's a different kind of visibility, and it doesn't show up in traditional rank trackers at all.
Can I check my AI visibility for free?
Yes. Ahrefs offers a free AI Visibility Checker with no signup, and both Surfer and AthenaHQ offer free plans with limited tracking. These give you a starting snapshot, though most serious ongoing tracking requires a paid plan.
How many AI engines should a tool track?
At minimum, look for ChatGPT, Perplexity, and Google AI Overviews, since those show up across nearly every comparison. If your audience also uses Gemini, Copilot, or Claude regularly, check whether the entry plan includes them or charges extra. Several vendors put those behind add-ons.
Do AI visibility tools fix my content, or just report on it?
Most just report. A smaller group, including Surfer and SearchBlueprint, pair tracking with actual content work. They edit existing pages or publish new ones aimed at the gaps the tracking data reveals. For broader strategy on this, see our SEO best practices for AI-driven growth.
How much should a small business budget for LLM optimization tools?
Budgets at the low end run $29 to $99 a month for a dedicated tracker like Otterly.AI or Semrush's toolkit. If you'd rather fold AI visibility into a broader SEO plan instead of buying a separate tracker, SearchBlueprint is worth a look. Its plans start free before moving to a paid Base or Agency tier.
Put One of These Tools to Work on Your AI Visibility
Choosing from the best LLM optimization tools for AI visibility starts with the free option that matches your biggest question. Use a quick checker if you want a snapshot, or a free plan if you want ongoing tracking without a bill yet. Once you know where you stand, the harder work is fixing what the data shows. That's where tracking tools alone run out of road. Maybe you'd rather see what an AI visibility and SEO plan built around your own site looks like before picking a tool.
